Also another thing occurs to me, you mentioned in your original
email that you were using a replace-always replacement scheme.
This is generally a poor choice for the normal hash table (it
works fine for the pawn hash table) since you are essentially
throwing away the information gleaned from deep searches for
shallow searches.  You might consider a draft-based or node-
based replacement scheme instead.  Using your current scheme,
it could be as Dennis mentioned, you might be overwriting the
needed (deep) search results with the information from
shallower searches.
